Ahh...were it so easy. Some of us have more than one priority. Especially single parents. Let's see, utilities, taxes, college tuition, and then there's retirement, various payments, kid needs, etc. Perhaps DG, like others no doubt, has much to consider. It seems adult, even cool, to take one's time with those alluring, expensive, carbon hussies. As for fitness, I'll bet you can drive your heart to perfection, indefinitely and if need be, on a Schwinn Varsity. Admittedly, not the slickest, but it works.
